• If you are trying to use Boolean operators, they must be ALL CAPS: %((middle east) OR (middle last)) %((2f foreign) OR (((2 foreign) OR (3 foreign)))) relations %((2f united) OR (21 united)) states%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((middle east) or (middle last)) %((2f foreign) or (((2 foreign) OR (3 foreign)))) relations %((2f united) or (21 united)) states%22".
• Adding a wildcard symbol may retrieve word variants: %((middle east) or (middle last)) %((2f foreign) or (((2 foreign) OR (3 foreign)))) relations %((2f united) or (21 united)) states%22*.
